To maximize the potential of the D800, use fixed focal length lenses and a tripod. If you need to hand hold, use a lens with VR optical stabilization, and the old adage of 1/shutter speed - double it. So 50mm shoot 1/125th, and so on, to ensure sharpness.

Pixel-peeping a D800 image needs these steps or you're just going to see blur, there is no real way around it.
